THlLL-OOUPLING.

SPECIFICATION forming part of Letters Patent No, 281,583, dated July 17,ieee,v

Application filed March 31, 1.883. `(Nomodel-.l

To a/ZZ whom it' may con/cern,

Beit known that I, GEORGE F. THOMPSON, or Oshkosh, in the county ofVinnebago and State of Wisconsin, have invented a new and usefulImprovement in 'Phill-Couplings; and I do hereby declare that thefollowing is a full and exact description of the same, reference beinghad to the accompanying drawings, and to the letters of reference markedthereon.

This invention relates to an improvement in thill-couplings, and isadapted to be applied to different sizes of axles, and to be readilyremoved and replaced .by anotherwhen so worn as to be unfit for use.

It consists in inserting between the two sections ofthe axle a bracketor other suitable device, to which the th-ills or shafts are coupled,and in irmly securing such device by means provided on its inner or thatend' passing through the axle, and by the ordinary clip, as will behereinafter described, and designated in the claims.

For a better understanding of my invention referencebmay be had to theaccompanying drawings, in which- 4Figure l is a perspective view of anaxle and thill coupled ink accordance with my in'- I vention; Fig. 2, a'vertical transverse section through the same, and Fig. A3 a view indetail of the device constructed in accordance with my invention. y

Like letters of reference indicate corresponding parts in each figure.

A and B represent the two sections coinposing the axle. The uppersection, A,which usually is made of wood, is provided on its undersurface with a depression or recess, c, v of a proper or sufficientwidth and `depth to admit a portion of the bracket O, which is insertedbetween the two sections of the axle. This portion of the bracketpassing between `the two sections of the axle is provided on its innerend, as shown, with two downwardlyprojecting hooks, b b, which claspfirmly the lower section, B, usually constructed of iron. On the frontend of the bracket @,and at a right angle to the portion passing throughthe axle, is an extension-plate, D, provided, as' shown, with twoforwardly-projecting ears, E E, between which the thill or pole iron ispivoted by means of the bolt c; The bracket Of thus described, is formedcomplete at one casting or forging, and when properly inserted betweenthe two sections of the axle is seclamped together.

l curely held in its position'by means of the clip 5 It will be manifestfrom the foregoing del scription of the bracket that it could beconstructed in a variety of ways without materially affecting itspurpose. For instance, the ears E E could be cast with bolts passingthrough the axle and secured by nuts on the other side, or the hooks b bcould be made to extend entirely across that portion with which they arecast, or could be forged with the hooks extending out straight andafterward bent up, so as to iit any size of axle, and other numerousmodifications could be made; but the present form will be found the mostpreferable, as itis best adapted to the accommodation of theordinaryclip, and is the simplest,cheapest, and most durable.

As will be apparent, no mechanical skill is required in applying thisdevice to the axle, nor is its application confined to a certain size ofaxle, but, on the contrary, it can be aflixed to any axle with butlittle change `in the same, and with but little time and labor.

What I claim, and desire to secure by Letter Patent, is-

I. A coupling device cast in one piece and inserted between the twosections of an axle,

' and rmly secured in its position by means of a clip, substantially asand for the purpose setl forth.

2. The combination, with an axle, as described, of a bracket insertedbetween the two sections of the same, and securely vheld therein bymeans of hooks cast or forged with vsaid bracket, and a clip passingover the axle, between said hooks and the ears of the bracket,substantially as described and shown.

3. The bracket C, cast or forged in one piece with the hooks b 1),extension-plate D, and the ears E E, substantially as described andshown.

' In testimony whereof I affix my signature in presence of twowitnesses.
